Hello Painisreal,
Let me be one of the first one to Welcome YOU to the group~! I'm glad you found us, but sorry that you had too. A couple of things first ... .how & when did you find out that your spouse is BPD? Feel free to tell us what you want because no one here in the group will judge you. We've been where you've are and know the pain, the hurt, the frustration, etc. We all have to walk our own BPD journey, but when you stumble on your BPD journey ... .and YOU will ... .turn around the group here will be here for you to help you up, dust you off, then the next step is up to you.
Some things to help get you started on your BPD journey. As Woods77 points out ... .be nice to yourself. You're probably going through so many things in your head ... .stop it. NOTHING YOU did or didn't say, did or didn't do is or will ever make a difference in your exBPDr/s. BPD is a Very Serious Cluster B Mental illness that even professional medical doctors, Ph.d's, Clinical Therapist can not fix ... .so what makes you think that you could have? Love does NOT conquer all. They are very seriously broken people ... .long before you entered into the picture ... .so take a deep breath and know that things are going to get better.
YOU need to start taking care of YOU~! You're so stressed out, not knowing what to say, do. So one of the first things you need to do is get rid of the enormous amount of stress you're going through right now ... .go for a walk before or after work. A mile will only take 15-20 minutes at a slow pace. Think about that for a moment, you can do 3 miles in an hour just by walking. This does a couple of things for you. It'll burn off some of those calories you've been stuffing in your face and it will reduce some of the physical & mental stress that is wreaking havoc on your mind and body.
Then start eating better ... .nothing good comes from junk food ... .not even your poo.

LOL ... .AND that is to remind you to get your humor back. Humor & laughter heals the mind body and soul. Watch a funny movie ... .better yet get together with a friend or several friends & get out to a comedy club. Stay away from the alcohol as much as possible ... .it's really a depressant and gives you a lot of empty calories that you really don't need anyway.
Find a good therapist ... .I can say and others hear will tell you that a really good therapist versed in BPD vs NON/codependent is one of the important key's of getting to the other side of your BPD canyon. They will help you sort out your emotions, feelings, thoughts into productive pathways forward. Chances are you are a Codependent aka a NON like the rest of us and they'll help you sort those things out & maybe you'll find out why you are the NON that you are.
Take notice of the small things in life because they are really the big things in life that we really never appreciate enough. Like on your walk in the morning, listen to the birds singing, the sun coming up. If it's in the evening after work then smell the fresh cut grass, or the flowers blooming or just enjoying the sun, the weather, nature.
This website has all kinds of resources at your fingertips to learn more about BPD. You'll learn about the BPD vocabulary like projection, gas-lighting, painted black/white, No Contact (NC) or Limited Contact (LC) etc. etc. etc. I would read a couple of books, "The Human Magnet Syndrome" "Stop Walking on Eggshells" ... .both which you can probably find in your therapist office, in your local library, or even online.
Your NOT alone ... .just like you ... .most if not all of us have been put through hell on a daily basis ... .and it will stop ONLY when YOU want it too ... .YOU got this ... .and the group has your back ... .

Here are a couple of video's for you to watch ... .one is motivational ... .one is funny as hell ... .& one is to let you know that it's ok to grieve ... .
